Neuregulin 1 or NRG1 is one of four proteins in the neuregulin family that act on the EGFR family of receptors. This growth factor was originally identified as a 44-kD glycoprotein that interacts with the NEU / ERBB2 receptor tyrosine kinase to increase its phosphorylation on tyrosine residues. NRG1 is a trophic factor that has been implicated in neural development, neurotransmission, and synaptic plasticity. NRG1 has multiple isoforms that are generated by usage of different promoters and alternative splicing of a single gene. Neuregulin 1 (NRG1) is essential for the development and function of multiple organ systems, and its dysregulation has been linked to diseases such as cancer and schizophrenia. NRG1 is a schizophrenia candidate gene and plays an important role in brain development and neural function. Schizophrenia is a complex disorder, with etiology likely due to epistasis.

Human Cells

A DNA sequence encoding the human NRG1 isoform alpha (Q02297-1) extracellular domain (Ser 20-Lys 241) was fused with a polyhistidine tag at the C-terminus.

Human

The secreted recombinant human NRG1 consists of 233 amino acids and has a calculated molecular mass of 25.5kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh NRG1 is approximately 40-45 kDa due to glycosylation.
